Declaring a new variable referencing a struct stored property variable (Stuct vs Class | Value Type vs Reference Type)

Question

In the Beginning iOS::Object-Oriented Swift::Structs vs Classes video starting at 3:04, Pasan states that a newly declared variable that references a struct stored property variable would be ignored and the original stored property would result.
This is not the case when I attempted to reproduce his statement. Is this a new feature within Swift 4?
Example:
```swift
struct User {
    var fullName: String
    var email: String
    var age: Int
}
var someUser = User(fullName: "Johnathan Maravilla", email: "fake@metastry.com", age: 33)
var anotherUser = someUser
anotherUser.email
someUser.email = "test@metastry.com"
print(someUser.email)
```

I figured it out. My code was incorrect:
swift
someUser.email = "test@metastry.com"

This line of code was outside of bounds and should have been under
swift
anotherUser.email

I was also calling the wrong instance when attempting to print and the result was as it should have been based upon what I was calling.
Side note: I found a blog post (https://developer.apple.com/swift/blog/?id=10) by Apple, explaining the differences between value types and reference types. it helped me understand the difference a bit more.
